stdio.h: move printf() stuff from <common.h> to <stdio.h>
<common.h> pulls in a lot of headers. Including it from every .c file is a bad idea. We need to remove contents until it contains nothing. Move printf() and friends to <stdio.h>. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
